I bought a Zeiss OTUS 85mm from BH rated 9+, but its hood fail to clamp on the body. So it is on its way back. I quickly tested it and left very impressed. It is definitely a twin brother of 55mm in rendering but with better CA and even slightly better Boekh, though with noticeable bigger size.
Both bokeh is a little boring to my taste I have to say. It is just very neutral, clear like water, Leica S lens is better to me in this regard but at slower speed. (Otus might be as good at f2~f2.5, didn\'t use enough to tell)
How good it is? think it this way, it has MP100 sharpness at f1.4 with better CA correction. A insane good lens. Will I get it again give me another chance? I am not so sure, this meant to be used as Portrait lens but focus throw design make it impractical for me, it is too long/slow for my preference. slightly movement of subject in my preferred working distance require quite a bit focus adjusting. (I had this complain of ZF85, this one is way worse. Leica R is still best in this regard)
DOF is redefined if you want fully taking advantage of WO of this lens, yes, lens is well corrected and easy to see focus with good after market screen. but plain of critical focus is super super thin with its focus throw design optimized for static stuff, it is not piratical to me. 55 also has long focus throw but I mainly use 55 for environment portrait, so I have a lot more DOF can use. and at that distance, the ratio of (subject move)/(throw turn) is good, means it is workable for me.
